Sigma just announced 18-35 F1.8!!! Anybody know if it will be out for pentax? Should be a good lens, price hasn't been announced yet. I guess it is going to cost a fortune.

Sometimes they announce them later for Sony/Pentax, sometimes not. I suggest contacting Sigma and asking for it.

Very true - I noticed that the new 35mm f/1.4 is now listed as available in a Pentax mount on the Sigma website. I have very high hopes that this 18-35 lens will find its way to Pentax as well. I have had very good experience with my limited number of Sigma lenses...

I was hoping Pentax would be the first to make an f/2 or faster zoom since they seem dedicated to APS-C. It would have really prevented the need for full frame at all, but then people start to realize that equivalent APS-C lenses are usually more expensive

For what it's worth though, the fast FF lenses are just as expensive (I'm looking at you, Nikon 24mm f/1.4).
